This 6 ring binder has the capability of holding a "page" for every color of cardstock, with the page being divided into thirds. With all of the colors stacked on top of one another in the book, you can mix and match the swatches just by flipping the different sections to your desired colors. This binder is perfect since it is something that could be updated easily as new colors were added to our collection. This is being made available for sale separately so for those of you who prefer to cut your own cardstock swatch pages may do so, but still have the convenience of having an official storage system. Please note, color cardstock inserts are sold separately. Dimensions: 7 1/2" x 9"
